UNITED STATES PATENT OFFICE.

GEORGE F. DIOKSON, OF CHICAGO, ILLINOIS, ASSIGNOR TO OONFEOTIONERS ANDBAKERS SUPPLY CO., A CORPORATION OF ILLINOIS.

BRINE-COOLING APPARATUS.

To all whom it may concern:

Be it known that I, GEORGE F. DIoKsoN, a citizen of the United States ofAmerica, and a resident of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Brine-Cooling Apparatus, of which the following is a specification. V

This invention relates to that type of brine cooling apparatus used inconnection with ice-cream freezers and the like, and in which the brinehas a continued circulation through the freezing jacket or chamber of anicecream freezer and through the brine cooling apparatus, and initspassage to the latter is sprayed upon a mass of salt and ice to acquirea reduced temperature; and the present improvement has for its object toprovide a simple and eflicient structural formation and combination ofparts whereby the brine after passing through the supply of ice and saltis very effectively screened from impurities, solid particles of ice,etc., before it returns to the freezing chamber, and with which theslime and floating impurities are removed in a ready and effectivemanner, all as will hereinafter more fully appear.

In the accompanying drawings :-Figure 1, is a longitudinal section online 03-02 Fig. 2. Fig. 2, is a plan view with the hopper removed. Fig.3, is a transverse section, on line w-ac, Fig. 1. Fig. 4, is a similarview on line 00 00-, Fig. 1. Fig. 5 is a similar view on line 00 -00Fig. 1. Fig. 6, is a detail horizontal plan on line w*w* Fig. 5.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings, 1 represents the main housing or casing ofthe apparatus, of an elongated rectangular form, and provided with aslanting bottom extending from end to end as shown.

3, is a transverse partition forming in connection with one of the endheads of the easing 1, a pit chamber for the suction pipe of thecirculating pump t of the apparatus, and which pump is mounted on thecover board of said chamber, as shown.

5, is a transverse partition forming in connection with the partition 3,a brine receiving chamber, at the top of which is arranged the ice andsalt containing chamber hereinafter described.

6, is a transverse partition forming in connection with the partition 5,a screen con- Specification of Letters Patent.

taining chamber, and in connection with the other end head of the maincasing 1, a collecting chamber for the floating impurities of the brine.

7, are passages formed in the partition 5, near its outer ends, andwhich afford communication between the brine receiving chamber and theouter or sub-chambers of the screen containing chamber, as shown inFigs. 1, I and 6.

S, is a transverse bar or dam at the bottom of the passages 7 aforesaid,to prevent the passage of solid particles of salt and the like from thebrine receiving chamber into the screen containing chamber.

9, are counterpart series of screens arranged longitudinally in screencontaining chamber, and located at opposite sides of the central line ofthe apparatus, as shown in Figs. 2,4 and (3, to divide the said chamberinto twoouter sub-chambers having communication with the passages 7aforesaid, and a central subchamber having communication with thelongitudinal duct hereinafter described, and by which the brine isconducted to the pit chamber of the pump. The screens will usuallyconsist of a. marginal frame and a center of wire fabric, and will beheld in a vertical position by the vertical guide pieces 10, securedtothe transverse partitions 5 and G, as shown.

The collecting chamber aforesaid is preferably of the hopper form shown,and formed by the angularly formed transverse partition 11, asillustrated in Fig. 3.

12, is an outlet duct or waste pipe connecting with the lower part ofthe collection chamber aforesaid.

13, are communicating passages between the screen containing andcollection chambers aforesaid, and formed in the partition 5, near itsupper end.

1 1, is a hopper arranged above the brine receiving chamber aforesaid,and provided with a perforated bottom preferably formed by a wire screen15, and transverse screen supporting rods 16, as shown in Figs. 1 and 5.Such hopper is adapted to contain a filling of broken ice and salt, uponwhich the brine as it returns from the freezing chamber or jacket of anice-cream freezer or the like is discharged in a series of small streamsfrom the perforated discharge head or pipe 17 arranged centrally andlongitudinally above the hopper as shown.

18, is a longitudinal duct, the casing of which extends from thepartition 3 to the partition 5 and is arranged centrally in the brinereceiving chamber aforesaid. Said duct at one end opens into the centralsubchamber of the screen containing chamber aforesaid, and at the otherend into the pit chamber of the circulating pump, as shown in Figs. 1,2, l, 5 and 6.

In the preferred form of the present invention the various partitions,covers, screen members and hopper are made removable with a view toafford ready access to the parts in cleaning the same, and to permit ofthe ready removal of a defective part and the substitution therefor of alike perfectpart. I

In the operation of the apparatus, the brine returning from the freezingchamber or jacket of an ice-cream freezer or the like is sprayed overthe mass of ice and salt in the hopper 1 1, and in trickling downthrough the same acquires the necessary reduced temperature. Passingdown through said hopper, the brine enters the brine re ceiving chamberat the sides of the casing of the longitudinal duct 18, in an evenlydivided manner, and flows therefrom into the outer sub-chambers of thescreen containing chamber, thence through the series of screens 9 intothe central sub-chamber of the screen containing chamber, and thenceback through the longitudinal duct 18 into the pit chamber of thecirculating pump 4 to be returned to the freezing chamber or jacket ofan ice-cream freezer or the like.

In its passage through the longitudinal duct 18, the brine acquires areduced temperature from the surrounding brine in the brine receivingchamber, to compensate for any loss in the passage through the screencontaining chamber.

The flow of the brine through the apparatus will ordinarily be so slowas not to interfere with the passage of the scum and lighter impuritiesfrom the screen containing chambers into the collecting chamber throughpassages 13.

Having thus fully described my said in vention what I claim as new anddesire to secure by Letters Patent, is

1. In a brine cooling apparatus, the combination of an ice hopper, abrine chamber arranged beneath the same, a screen eontaining chamberarranged at one end of the brine chamber, a pump chamber arranged attheother end of the brine chamber, and a longitudinal duct passing throughthe brine chamber and connecting the screen cont-aim ing chamber withthe pump chamber, substantially as set forth.

2. In a brine cooling apparatus, the combination of an ice hopper, abrine chamber arranged beneath the same, a screen containing chamberarranged at one end of the brine chamber, a pump chamber arranged at theother end of the brine chamber, and a longitudinal duct connecting thescreen containing chamber with the pump chamber, and arranged centrallyin the brine chamber, substantially as set forth.

3.

4. In a brine cooling apparatus, the combination of an ice hopper, abrine chamber arranged beneath the same, a screen containing chamberarranged at one end of the brine chamber, a pump chamber arranged at theother end of the brine chamber, a longitudinal duct connecting thescreen containing chamber with the pump chamber and a collecting chamberarranged at the end of the screen containing chamber and communicatingtherewith near its top, substantially as set forth.

5. Ina brine cooling apparatus, the combination of an ice hopper, abrine chamber arranged beneath the same, a screen containing chamberarranged at one end of the brine chamber, a pump chamber arranged at theother end of the brine chamber, a longitudinal duct connecting thescreen con? taining chamber with the pump chamber and a collectingchamber having a hopper form and arranged at one end of the screencontaining chamber and communicating therewith near its top,substantiallyas set forth.

6. In a brine cooling apparatus, the combination of a centrally locatedice hopper, a brine chamber extending horizontally beneath the same, apump chamber arranged at one end of the brine chamber, and alongitudinal duct passing horizontally through the brine chamber andconnecting a remote end of the same with the pump chamber, substantiallyas set forth.
